Cooperative sound design: a protocol analysis
2016
Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.
Ultra Reliable Communication in 5G Networks: A Dependability-based Availability Analysis in the Space Domain
2017
Master's thesis Information- and communication technology IKT591 - University of Agder 2017 As our daily life is becoming more dependent on wireless and mobile services, seamless network connectivity is of utmost importance. Wireless networks are expected to handle the growing demand for applications which require higher capacity, without failure. Therein, wireless connectivity is regarded as an essential requirement for a wide range of applications in order to support exible and cost-e ective services. As part of the fth generation (5G) communication paradigm, ultra reliable communication (URC) is envisaged as an important technology pillar for providing anywhere and anytime services to en…
Collaborative Design Rational and Social Creativity in Cultures of Participation
2011
The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…
Theoretical approaches and frameworks to language maintenance and shift research : a critical review
2019
This article presents a critical overview of theoretical approaches and frameworks to language maintenance and shift research in the area of immigrant languages. It covers the underlying principles of these frameworks and assesses their advantages and shortcomings. The article argues that the field’s theoretical orientations have shifted recently, with a greater emphasis on understanding language maintenance and shift as a dynamic process involving complex interrelationships between space and time. These new trends and new areas of research in relation to language maintenance and shift are highlighted and discussed in different parts of the article. The article concludes by calling on the s…

Investigation of the Sympathetic Regulation in Delayed Onset Muscle Soreness: Results of an RCT
2021
Sports-related pain and injury is directly linked to tissue inflammation, thus involving the autonomic nervous system (ANS). In the present experimental study, we disable the sympathetic part of the ANS by applying a stellate ganglion block (SGB) in an experimental model of delayed onset muscle soreness (DOMS) of the biceps muscle. We included 45 healthy participants (female 11, male 34, age 24.16 ± 6.67 years [range 18–53], BMI 23.22 ± 2.09 kg/m2) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative). The aim of the study was t…
Des sacrifices sans consommation : les dépôts d'animaux non consommés en Gaule romaine
2002
International audience; À la période romaine, des dépôts d'animaux sont effectués dans des lieux relativement isolés, à l'écart des villes ou à proximité de certaines agglomérations. Ces dépôts dans des fosses ou des puits concernent des animaux non consommés, déposés entiers et sélectionnés en fonction de leur sexe et leur âge. Ils sont parfois accompagnés de certains objets particuliers, comme des vases miniatures ou des couteaux, qui peuvent être considérés comme des offrandes et qui montrent alors que nous ne sommes pas en présence d'une pratique profane, l'enfouissement d'un animal pouvant intervenir dans bien des circonstances et répondre à bien des préoccupations, comme de se débarra…
Behind the scenes of artificial intelligence: a study of micro-work platforms in France
2019
Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
2007
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newton X-ray observatory to study the thermal structure, variability, and long-term evolution of hot plasma, to investigate the magnetic dynamo, and to search for new potential members of the association. Many targets are also studied in the optical, and high-resolution X-ray grating spectroscopy has been obtained for selected bright sources. The X-ray spectra have been coherently analyzed with two different thermal models (2-component thermal model, and a continuous emission measure distribution model). We present ov…
Spectral properties of X-ray bright variable sources in the Taurus Molecular Cloud
2006
We analyze 19 bright variable X-ray sources detected in the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), in order to characterize the variations with time of their coronal properties and to derive informations on the X-ray emitting structures. We performed time-resolved spectroscopy of the EPIC PN and MOS spectra of the XEST sources, using a model with one or two thermal components, and we used the time evolution of the temperatures and emission measures during the decay phase of flares to derive the size of the flaring loops. The light curves of the selected sources show different types of variability: flares, long-lasting decay or rise through the whole observation, sl…
